I propose for you 4 single levels for Z(95) (of mod "Hard Ordeal").
Execute on version Z(95) for Windows XP. This is modification for hardcore gamers. These present levels this is demonstration of opportunities to modification Z1.
Download - http://generalzod.narod.ru/file/Cachatka/modZ_XP.rar

Installation:
- Unarchive
- Place contents of archive "modZ_XP.rar" in a folder with game (folder LEVEL01, LEVEL02, LEVEL03, LEVEL12). They will replace the originals.
- Start new game (levels 1, 2, 3, 12 not such, as before)

====== Commentary =========
In first three levels (1, 2, 3) everything has changed, aside from a landscape.
Overpatching:
- Quantity of units and factories
- Types of military objects
- Startpoints
- Tasks of the computer player in the beginning
- AI (as far as possible)

It thoroughly change habitual gameplay.

The card "12" demonstrates a way of changes of a landscape. Singl map to release from multiplayer level! It is clear you could not see this card in original game. Up to the present it is a unique way to receive a new level for Z. Problems not exist about Z98. ZEDITOR allows to make new single add-on. However there is no opportunity to convert maps Z98 up to map Z95 (I do not know as it is possible to make). The opposite convert to present no difficulties just as convert map Z95(XP) up to map Z95(DOS). There is a description in Russian - http://generalzod.narod.ru/file/doki/Z_03.rar
I can do make it, if there is a necessity.

Thanks again. I can play now. But I have one question regarding sound and midi. In the game I have no sound at all at first. So I copy AUDIO directory from z95 cd to c:\z and now I have soldiers voices (like: What are you waiting for...) but I don't have midi music and sfx sounds (like shooting and exploding). Is any way to fix this?

And is it even possible to finish first level?? I mean, computer has small, medium and heavy tanks, and I have jeeps and no defense on port. Isn't a bit hard?

The first release of Z was based on DOS. Playing it under Windows 95 was possible but often very problematic. The Bitmap Brothers realized that the Windows platform was becoming much more popular and redesigned the game a little so it could be installed and run under Windows 95. In 1998 they called the new version "Z95 + Expansion Kit" since they put some new levels, a Windows desktop theme and a multiplayer-level-editor on top. Z95 is still not a true Windows application though. For example you cannot take screenshots from the game using the Windows API functions. When Windows 98 came out the Bitmap Brothers even had to produce a little patch in order to make the setup routine work under Windows 98 (look for the patch on my help page).
